Info to debunk global warming deniers

Stages of Denial
There's nothing happening
Inadequate evidence
There is no evidence
One record year is not global warming
The temperature record is simply unreliable
One hundred years is not enough
Glaciers have always grown and receded
Warming is due to the Urban Heat Island effect
Mauna Loa is a volcano
The scientists aren't even sure
Contradictory evidence
It's cold today in Wagga Wagga
Antarctic ice is growing
The satellites show cooling
What about mid-century cooling?
Global warming stopped in 1998
But the glaciers are not melting
Antarctic sea ice is increasing
Observations show climate sensitivity is not very high
Sea level in the Arctic is falling
Some sites show cooling
No consensus
Global warming is a hoax
There is no consensus
Position statements hide debate
Consensus is collusion
Peiser refuted Oreskes
We don't know why it's happening
Models don't work
We cannot trust unproven computer models
The models don't have clouds
If aerosols are blocking the sun, the south should warm faster
Observations show climate sensitivity is not very high
Prediction is impossible
We can't even predict the weather next week
Chaotic systems are not predictable
We can't be sure
Hansen has been wrong before
If we can't understand the past, how can we understand the present?
The scientists aren't even sure
They predicted global cooling in the 1970s
Climate change is natural
It happened before
It was warmer during the Holocene Climatic Optimum
The medieval warm period was just as warm as today
Greenland used to be green
Global warming is nothing new!
The hockey stick is broken
Vineland was full of grapes
It's part of a natural change
Current global warming is just part of a natural cycle
Mars and Pluto are warming too
CO2 in the air comes mostly from volcanoes
The null hypothesis says global warming is natural
Climate is always changing
Natural emissions dwarf human emissions
The CO2 rise is natural
We are just recovering from the LIA
It's not caused by CO2
Climate scientists dodge the subject of water vapor
Water vapor accounts for almost all of the greenhouse effect
There is no proof that CO2 is causing global warming
Mars and Pluto are warming too
CO2 doesn't lead, it lags
What about mid-century cooling?
Geological history does not support CO2's importance
Historically, CO2 never caused temperature change
It's the sun, stupid
Climate change is not bad
The effects are good
What's wrong with warmer weather?
The effects are minor
Change is normal
Climate change can't be stopped
Too late
Kyoto is a big effort for almost nothing
It's someone else's problem
Why should the U.S. join Kyoto when China and India haven't?
The U.S. is a net CO2 sink
Economically infeasible
Climate change mitigation would lead to disaster
